Scalability - Hitachi G1000 Hardware Manual

Scalability

The storage system offers an entirely new type of scalable and adaptable
integrated active-active architecture that supports integrated management.
Hitachi Data Systems storage systems can be configured in numerous ways
to meet performance and storage requirements.
Scalable system performance
System performance can be optimized according to the needs of the user and
can be easily upgraded (in small or large increments) as storage needs
increase. The following table shows the supported configurations.

Notes:
1. A VSD pair consists of two VSD blades. Each VSD contains one 8-core processor.
2. Cache memory modules can be either 16 GB or 32 GB, but only one memory module size can be
used in a system.
3. HDS minimum cache per system is 64 GB whether the system contains one or two controllers.
